Application

Features

Steel grades for example

Commercial purposes

With some ductibility, they are suitable to simple forming, bending or welding

DC01, SPCC, St12

Drawing

With more ductibility than the common ones, they are suitable to manufacturing parts through drawing and relatively complicated deforming

DC03, SPCD, St13

Deep drawing

With more ductibility and homogeneity than the drawing ones, they are suitable to manufacturing parts through deep drawing and complicated deforming.

DC04,SPCE,St14

Extra-deep drawing

With more ductibility and homogeneity than the deep drawing ones, they are suitable to manufacturing parts through extra-deep drawing and more complicated deforming.

DC05, SPCF, St 15

Supreme extra-deep drawing

With more excellent drawing capability than the extra-deep drawing ones, they are suitable to manufacturing parts through supreme extra-deep drawing and extremely complicated deforming.

DC06, SPCG,  St16
